Graham said she was bullied multiple times through texts, Facebook and verbal attacks by a handful of students. After several months, it turned physical inside a high school cafeteria.

“She comes up behind me and climbs onto the top booth and starts just pounding my head in for a good one minute,” said Graham.

While the girl who attacked Graham was suspended, Graham’s father said the school failed to provide answers or take the warning signs seriously.

“They wouldn't tell me what the charges were, wouldn't tell me anything about it,” said Timothy Graham. “Let’s bring parents in and make them understand their children are either going through this or causing it, one or the other.”

Defense attorney Pat Thomassey has said it looks like some kind of "bullying events" may have happened to 16-year-old Alex Hribal before he was arrested Wednesday after 21 students and a security guard were stabbed inside the high school.

Alicia Graham said one student posted mean comments about the boy on Facebook the night before the stabbing.

“He was basically just calling Alex out, called him a 'rat face' and said other rude things on his post,” she said.

She said the post was deleted the day of the stabbing, but her friend had already saved a screen shot that’s been turned over to police.

The girl who attacked Alicia Graham is expected to return to school this month, but she’s focused on helping her friend’s from Wednesday’s stabbing recover.
